Tomasz Dajczak - "Eureka (Theme / Song 4)" -- Chiptune Visualization / Atari SAP (NEW ALGORITHM)
41*** PLEASE, WATCH IN HIGH QUALITY FOR PROPER AUDIO! ***
So, I decided to take a look at all the separate channels of some chiptune music at once. Thought it might look cool, since those waveforms are usually so pretty.
This is a video made with a complete rewrite of my original Python script, which I'll be releasing to the public soon after a few more tweaks to the algorithm.
I finally got around to implementing my "TimbreCapture" algorithm, which finds the exact waveform shape being repeated for a note (the timbre's minimum waveform) and consistently centers it on screen. (Although, like in this video, I think it looks better when it's NOT centered and is anchored on the left side.)
This way we can always see the exact shape of the wave being played at any given moment and how it changes.
It's working well so far (misses a few weirder waveforms), but I still need to add a couple more features to it.
I'm trying to figure out what's the ideal way to handle those very fast note changes/arpeggios. For now, I'll be trying it out on some shorter and lesser known songs (which I still think are nice) just to get more stuff out there and try the new algorithm out in different cases.
Stay tuned for the source code soon.
Oh, and there's more! I'm also going to be releasing the source code for my tool to convert POKEY dumps to MIDI files. These will require a modified version of asapscan from the ASAP library.
